Do participants read
informed consent forms?
Dwell time on consent: Reading speed (as words per minute):
Additional coding
Do participants read
informed consent forms?
replication part
expansion part
Taking into account prior knowledge regarding research data handling
Structural model only (without measurement models)
Trouble with dwell_time being skewed? -> log-transform?

fit <- lavaan::sem(fit, data = data)
summary(fit, standardized = TRUE, fit.measures = TRUE)
Does the information on sharing data influence the participants’ willingness to participate?
